Muskogee County, in Oklahoma, sits in USDA hardiness zone 7b — a range where zone-matched perennials and frost-aware annual timing set what succeeds.
A short list that earns its place here — pecan, tomato, okra, and redbud — with any one site's soil, sun, and drainage making the final cut.

Soil in Muskogee County
Across Muskogee County, the ground is predominantly Mollisols, where Dennis, Bates, and Taloka are the most extensive named soil series. The soil is generally well drained with a silt loam surface. Topsoil pH runs about 5.6–6.1, moderately acidic. Rainfall drains through hydrologic group D soils.

Is it too late to plant in Muskogee County?
For most of the year, no — what changes is which crops still fit the days remaining. Cool-season crops can go in from around Jan 17; tender transplants wait until two to three weeks after the last 28°F hard freeze, which lands near Feb 14 (NOAA 1991–2020 climate normals); and from midsummer, planting counts back from the first fall freeze around Dec 13 — long-season crops need about 90 days of runway, quick greens only 30. With almost year-round growing weather, timing is about heat and rainfall more than frost — some bench is always in play.

Growing Challenges in Oklahoma
What an experienced grower plans around here — each one has a move.

Extreme weather variability (tornadoes, ice storms, drought)
Flexible beats fortified here: row covers staged, storm-tough perennials, and quick-replant annual beds.

Red clay soils drain poorly in central OK
A raised bed ends the standing-water fight in a weekend, and fall compost keeps opening the clay below.

Low western rainfall requires irrigation
Western plots run on drip and mulch — plan the water before the planting and the dry years lose their teeth.
For cultivar selection, pest pressure, and planting-time guidance specific to Oklahoma, the Oklahoma State University Extension is the authoritative local source.
Safe to Grow Here?
What the federal record shows across Muskogee County — and how to grow with it.
We checked the federal record across Muskogee County — 388 documented sites across 6 of the 9 source types we track.
The most significant on record: 3 Superfund sites. Sites tracked in EPA's Superfund program — from assessment-stage CERCLIS entries to confirmed National Priorities List cleanup sites.
Muskogee County carries one of the heavier federal records we track — and that's not a verdict on your yard. Proximity to a documented site is information, not a diagnosis: nothing here says any particular parcel is affected. It does earn one concrete step — before food beds go in the ground, a professional soil test tells you exactly what you're working with, and raised beds with clean imported soil grow well almost anywhere in the meantime.

A note from Gnorman
What an experienced grower watches for around here
In and around Muskogee County, two things run higher than the national average — PFAS (6 sites) and Toxic Release Inventory (35 sites). That's not a problem with your land — it's information about it.
PFAS: PFAS (per- and polyfluoroalkyl substances) are called "forever chemicals" because they do not biodegrade.
Toxic Release Inventory: TRI facilities report annual chemical releases to air, water, and land.
Test irrigation water source — this is the primary pathway for PFAS to reach garden crops.
Check prevailing wind direction — downwind parcels face higher exposure than upwind or crosswind locations.

Frequently Asked Questions
What hardiness zone is Muskogee County, Oklahoma?
Muskogee County sits in USDA hardiness zone 7b, per the USDA Plant Hardiness Zone Map 2023. Zones reflect average annual extreme minimum temperatures from 1991–2020 weather data.
Is it too late to plant in Muskogee County?
For most of the year, no — what changes is which crops still fit the days remaining. Cool-season crops can go in from around Jan 17; tender transplants wait until two to three weeks after the last 28°F hard freeze, which lands near Feb 14 (NOAA 1991–2020 climate normals); and from midsummer, planting counts back from the first fall freeze around Dec 13 — long-season crops need about 90 days of runway, quick greens only 30. With almost year-round growing weather, timing is about heat and rainfall more than frost — some bench is always in play.
When does frost risk typically end in Muskogee County?
The last hard freeze (28°F) in Muskogee County typically lands around Feb 14, per NOAA 1991–2020 climate normals — an earlier marker than the light-frost dates many planting charts quote. That marks the hard freeze, not the last light frost — light frosts can still bite for a few more weeks, so tender transplants usually wait another 2–3 weeks.
How long is the growing season in Muskogee County?
Measured between 28°F hard freezes, Muskogee County sees about 302 frost-free days — roughly Feb 14 through Dec 13, per NOAA 1991–2020 climate normals. Tender crops get a somewhat shorter practical window, since lighter frosts reach a few weeks past the hard-freeze dates on both ends.
What vegetables grow in Muskogee County?
Muskogee County's zone 7b supports a wide range — strong performers include Pecan, Tomato, Okra, Redbud, and Blackberry. What actually takes on any one site comes down to its soil, sun, and drainage, and we score each plant against the real conditions at your address.
Which hardiness zone is Muskogee County, really?
Officially, Muskogee County sits in USDA zone 7b (USDA PHZM 2023) — but a zone is a 30-year average of winter's coldest night across an area, and it can't see any one yard. A south-facing slope, a tree line, or a low frost pocket can shift a single site by half a zone either way, which is why neighboring gardeners often quote different numbers. We read the conditions at your exact address — soil, sun, slope, and frost — and score 1,112 plants against what's actually there.
Is the soil safe to grow vegetables in Muskogee County?
The federal record around Muskogee County runs heavier than most — 388 documented sites — so test the soil before planting food in the ground, and raised beds with clean imported soil grow well in the meantime. Even here, proximity to a documented site is information, not a diagnosis of any one yard; the contamination map shows exactly what's recorded and where.
Just moved to Muskogee County — what should I know before planting?
Start with three facts. Muskogee County sits in USDA zone 7b, which sets what survives winter; the last 28°F hard freeze typically clears around Feb 14, with about 302 frost-free days to work with (NOAA 1991–2020 climate normals); and 388 documented sites sit on the federal record here, so a soil test before food beds is the smart first step. From there, matching plants to your actual soil and sun is the fun part.
Everything on this page is a Muskogee County average. Your yard writes its own version — we read soil, sun, drainage, and frost at your exact address. Try it for 14 days — no card required.
